OS-QUICK, a universal quick connect coupling kit available as optional equipment from Hoshizaki America, is recommended. 4) Use an electronic leak detector or soap bubbles to check for leaks. Add a trace of refrigerant to the system (if using an electronic leak detector), and then raise the pressure using nitrogen gas (140 PSIG).
  • Page 18 c. Make sure the male fitting and female coupling are properly aligned, then start the connection by hand to ensure that it is not cross threaded. d. Tighten the connection with a wrench until it is tight. At this point, the nut has covered most of the threads on the male fitting.

    10 PSIG. Do not run the icemaker until the proper water pressure is reached. • A plumbing permit and services of a licensed plumber may be required in some areas. • External filters, strainers, or softeners may be required depending on water quality. Contact your local Hoshizaki distributor for recommendations. • Water supply pressure should be a minimum of 10 PSIG and a maximum of 113 PSIG. If the pressure exceeds 113 PSIG, the use of a pressure reducing valve is required. • The icemaker and condensation drain line(s), storage bin drain line, and water-cooled condenser drain line (if applicable) must be run separately.
